Hi,
This could be an alcohol intolerance.
Alcohol can cause effects on the body such as headache, rapid heartbeat, nausea or vomiting,
heartburn, abdominal pain, nasal congestion, or warm, red, itchy skin. With intolerance, you are more sensitive to these effects compared to other people. In particular, many people of Asian descent experience an unusual flushing reaction after drinking alcohol. This is due to a genetic disorder in which the body is unable to break down alcohol completely.
